BOWL CLAMP ron CREAM SEPARATORS.

Application filed December 4, 1919. Serial No. 342,344.

To allwhom it may concern:

Be it known that ALroN L. BAUGHMAN, a citizen of the United States of America, residing at Wolf Lake, in the county of Noble and State oi Indiana, has invented new and useful improvements in Bowl Clamps for Cream Separators, or which the following is a specification.

The object of the invention is to provide means for engaging and holding the bowl of a cream separator after the removal of the reservoir while the cap or plug with which such bowls are usually fitted, and by which they are closed at the top, and which usually have a threaded engagement with the bowl, and are ordinarily designated as bowl nuts, is loosened or tightened in the act of removing or replacing the same.

As will be understood by those familiar with the art these bowl nuts are usually en gaged with the-bowls under such circumstances as to necessitate firmly holding the bowl while thenuts are being either loosened or tightened, and owing to the fact that the surface of the bowl is more or less covered particularly at the end ofthe separating operation witha coating of milk and grease, it is necessary to employ mechanical means for holding the same, and ordinarily the prac tice is to remove the bowl from the separator and apply it to a clamp or holder located on some adjacent convenient support during the manipulation of the cap or nut, and it is in order to avoid the necessity of thus removing and replacing the bowl that the clamp forming the subject matter of this invention has been devised, the purpose be? ingto form the clamp as a part of the separator or to provide for attaching the same so that it may remain in position during the ordinary operation of the separator and in operative relation with the separator at all times, to the end that when the separat ing operation hasbeen. completed and the reservoir removed together with the cream and milk spouts which are located abovethe skimming bowl, the operator may proceed at once to detach the cap or nut so as to permitjogf-tlie cleansingofthe bowl without the loss of time an'd'inconvenience incident to the removalthereof from the machine as above; indicated.

With these objects view the intention consists in a construction and combination of parts of which a preferred embodiment is illustrated in several analogous forms in the accompanying drawings, wherein:

Figure 1 is a perspective view oi the clamp seated upon a reservoir bracket and designed to remain permanently in position thereon to constitute with the bracket a seat for a skimming bowl of the ordinary construction.

Figure 2 is a view of the clamp applied to a form of reservoir bracket wherein a different modification of the reservoir bracket is involved. 7 Figure 3 shows the clamp proper applied to still another modified form of the bracket.

Figure el shows a. modified construction of the bracket shown in Figure 3 wherein an increased area of support for the bowl is provided.

Figure 5 is a view of the clamp associated with a bowl seat which is formed independently of and is applicable to the ordinary construction of reservoir bracket, to provide for the'utilization of the bowl holding means in connection with a separator having the common form of reservoir bracket.

Figure 6 is a sectional view showing the application of the form of holder shown in Figure 5 applied to the reservoir bracket.

Figure is a plan view of the clamp applied to a bracket similar to that shown in Figure 8 and indicating in dotted lines the deflected or bowl, engaging position of the flexible clamp member,

'Figure 8 is a plan view of the separable form of clamp and seat similar to that shown in Figure 5.

Figure 9 is a plan view of the clamp applied to a seatring similar to those shown in Figures 5 and8 and illustrating a different form or" attachment of the extremities of the band to said ring.

Essentially the clamp consists of a fiexible, inelastic, resilient or separating band 10 (referring particularly to Figure 1 or the drawings) formed of a ribbon of steel, brass or similar material and preferably of metal or of such a substitute as will inbeing designed, to bound a circular open space of a diameter sufficient to receive a skimming bowl of the ordinary construction used in centrifugal separators as indicated in Figure 6 at 11, and said band further be ing anchored atone side of the space bound thereby at spaced points indicated in Figure 1 at 12 under such conditions as to permit of the bodily deflection of the band in its own plane to cause a contraction of the space bounded by the dotted lines in Figure 7.

In practice it has been found desirable to construct the band of a continuous strap or ribbon of material having the required resilience or separating quality its extremities turned back or folded upon themselves to provide loops or eyes for engagement with studs 14: spaced apart to an extent sufficient, when the band deflected laterally in one direction or the other in its own plane as shown by the dotted lines in Figure 7, the contraction or reduction of the space bounded thereby will be such as that while a bowl may be fitted freely thereinto when in its normal or circular form, it will be firmly clamped by reason of such lateral deflection to a comparatively small extent in either direction so that whether the bowl nut is being turned in one direction or the other as in either loosening or tightening, the tendency of the bowl to move laterally under the strain thus'applied to the nut will cause a sufiicient deflection of the band to cause the latter to firmly grip and hold the bowl.

The extremities of theband when constructed to form eyes or loops 13 are adapted to swing freely upon the studs to permit of the'lateral deflection of the body portion of the band, a corresponding construction being illustrated in Figure 7 and said studs are preferably arranged upon a bowl seat which in the construction illustrated in Figure 1 is formed bytransverse or horizontal extensions or enlargements 15 of the arms 16 of the ordinary reservoir bracket which. in the usual construction of cream separators of the centrifugal type are provided with. three radiating arms constituting a spider of which the intersection 17 forms a portion of the bowl seat and which in the form of the invention illustrated in Figure 1 is included within the area bounded .by the clamping band; 10. The band at spaced points bears upon seats 18 formed by adjacent portions of the arms of the bracket.

In the construction illustrated in Figure 2 the band 10 corres onds with that above described including t e terminal eyes or loops 13 for engagement with the studs 1 1 which are spaced apart to serve as anchoring means for the band and cause a distortion of the band and a consequent contraction or reduction of the area bounded by the band whenthe latter is deflected laterally in either direction in its own plane, but in this-form or applicathe arms of the reservoir bracket.

or tightening the bowl nut will cause a sufficient deflection of the band to insure a firm clamping action of the latter upon the surface of the bowl to hold the latter against rotation.

In the construction illustrated in Figure 3 a different arrangemnt of enlargement 15 for supporting the studs 14 for engagement by the terminal eyes or loops 13 of the band 10 is illustrated, although functionally the parts have the same qualities as those heretofore indicated, while in Figure 1 the enlargement 15 which supports the band anchoring studs 1r is supplemented by seats 19 formed as extensions'of the several arms16 of the reservoir bracket.

In Figures 5 and 6 the bowl receiving and engaging band 10 is terminally engaged with studs 1 1 supported by a ring 15 which is formed independently of the reservoir bracket and is provided with depending ears 20 arranged in pairs and spaced apart as shown in Figure 5 for engagement respectively with'the arms of an ordinary reservoir bracket so that this construction of clamp may be applied to the ordinary form of separator Without modifying the construction of the bracket while all of the advantages of holding the bowl in position during the removal and replacement of the bowl nut are secured, the location of one pair of the cars 20 with reference to a bracket arm 21 being indicated in Figure 6.

In Figure 7 as hereinbefore indicated the band 10 corresponding in construction with those shown'in other figures is indicated in dotted lines in a laterally deflected position as when contracted to firmly engage the bowl during the. adjustment of the bowl nut, the anchoring elements or studs 14L with which the terminal eyes or loops 13 are engaged being supported by a web 15 connecting two of the arms 16 of the reservoir bracket while in Figures 8 and 9 the forms of bowl support illustrated are of the general type indicated in Figure 5 wherein the bowl and band supporting'rings are formed independently of Moreover in Figure 9 a modification is illustrated in the matter of the attachment of the terminals of the band 10 in that its extremities are curved to form eyes 13 having radial explacement or lateral movement of the body portion of the band in its own plane as described in reference to the other forms of the device without permitting the turning of the eyes upon said anchoring studs.

What is claimed is:

1. The combination with the bracket of a cream separator having supporting means for the reservoir, of a bowl clamping device within the reservoir supporting means, comprising a flexible metal band anchored at its ends to said bracket, there being a support for the band and the bowl to be clamped thereby within the reservoir supporting means.

2. A cream separator bracket provided with a series of spaced apart reservoir supporting members arranged along a common circumference described from approximately the center of the bracket and provided also with a circumferentially continuous band support Within the first named circumference, and apair of studs on the last named support for the reception of the ends of the band.

3. A combined reservoir, bowl and bowl clamp support comprising a bracket provided with a series of somewhat upwardly extending radial arms each shaped at the end to provide a rest and an abutment, and two relatively closely arranged studs both located at substantially the same distance from the center of the bracket but at a substantially shorter distance from the center of the bracket than the ends of said arms, said studs adapted to engage the ends of a flexible non-stretchable embracing band, the bracket being adapted to support the band and bowl. throughout at least a part of their circumferences.

In testimony whereof he aflixes his signature.
